from The Vintagent: 'ROSIE' THE DKW SS350
These racers also have a Ladepumpe under the the engine, which is a separate cylinder (and crankshaft, on the Works machines) used to compress air into the crankcase - a kind of supercharger for two-strokes. Thus, while this motorcycle is technically a twin-cylinder two stroke, mechanically it is a 5-piston machine - hardly a 'simple two-stroke'. The SS350 produced around 34hp, and used magnesium for the crankcases, gearbox case, and brake hubs, and was what DKW offered to the public for racing. According to Wolfgang Schneider, this complicated multi-piston two-stroke engine is only competitive for racing when the extra 'push' of the Ladepumpe piston is used.
